Keith, thanks again. I found John and Thomas in Ohio Co. In the 1810 census, John is on the same record sheet as Stephen Burkham, later Nancy's father-in-law, so it's likely that the families were living in the same vicinity. John's household includes four female children under ten, one of whom could have been Nancy. We may never be able to verify the connection, but it makes sense and is by far the best possibility I've found to date. I'll keep working on it. -- Kate
